Good morning #JFokus!👋 Make sure to catch @ssmith.bsky.social and @fniephaus.com to ask anything you want to know about GraalVM & WebAssembly, and attend their session on Wednesday!

GraalVM 25.0.2 is now available! 🚀 Upgrade to get the latest security updates and improvements. Release notes: www.graalvm.org/release-notes/ Downloads: www.graalvm.org/downloads/

WasmGC is coming to GraalWasm, unlocking the power of JVM garbage collectors for #WebAssembly! This will also get GraalWasm a lot closer to implementing the full Wasm 3.0 spec. Join @ssmith.bsky.social and me at @jfokus.se next month to learn more: www.jfokus.se/talks.html?s...

I'm really looking forward to @jfokus.se which is coming up soon! It's always a great conference and you might still be able to find tickets so you can join @fniephaus.com and me as we sail our longship to the mysterious lands of #WebAssembly and @graalvm.org.

Native Image is an *amazing* technology! Having a 150mb+ JAR full of weird compiler stuff (from jrtfs to Swing!) in kotlinc quite easily built with Native Image, and immediately yielding this kind of improvement is outstanding. Looking forward to what's next 👀

The @kotlinlang.org team at @jetbrains.com is working on a @graalvm.org-compiled kotlinc. Early experiments look very promising: > So far, a native image with PGO offers a properly "warmed-up" kotlinc and with up to 20% more peak throughput. Ticket: youtrack.jetbrains.com/issue/KT-823...

Excited about @quarkus.io latest update, including first-class support for JavaScript, Python, and Wasm – powered by @graalvm.org! 🚀

Nice demo from @fniephaus.com from the @graalvm.org team of a Spring Boot application summarizing various files with MarkItDown and Hugging Face Transformers popular Python libraries with GraalPy. github.com/fniephaus/gr...

It’s live! "@graalvm.org meets #WebAssembly” from @devoxx.com: compile JVM apps to Wasm (Web Image) and run Wasm in Java or Kotlin at near‑native speed (GraalWasm). Lots of live demos included! www.youtube.com/watch?v=uefc...

Spring Shell running on the browser thanks to WebAssembly, cool demos by @fniephaus.com Repo: github.com/graalvm/graa... #DevoxxBE

Excited to talk about @graalvm.org and #WebAssembly tomorrow at @devoxx.com! 🚀 Join me to explore Web Image and GraalWasm — and see them in action with plenty of live demos.

Big update for GraalVM's AOT compilation in the making! 🔥

The new @graalvm.org 25 release is now available in the @intellijidea.com JDK downloader!🎉 Grab it while it's!🔥 www.jetbrains.com/guide/java/t...

Fabio @fniephaus.com will introduce Web Image, a new preview feature of GraalVM that enables compiling applications into efficient Wasm modules, including use cases and live demos. We'll also look at GraalWasm, a new embeddable Wasm runtime. m.devoxx.com/events/dvbe2...

GraalVM 25 released today! 🎉 My favorites this release👇

TruffleRuby 25.0 is released! 🚀🎉 It can now run native extensions in parallel, just like Ruby code already ran in parallel in Threads on TruffleRuby! It also features many compatibility improvements and notably support for custom Digest algorithms. github.com/oracle/truff...

#GraalVM 25 is out! 🚀 Exciting updates for #GraalPy, #GraalJS, and #GraalWasm — plus our first preview of #WebAssembly compilation!

Excited to be back at @Devoxx Belgium—this year talking about @graalvm.org and #WebAssembly! Don’t miss what’s next for Java & Wasm. 🙂 m.devoxx.com/events/dvbe2...

Want to build, debug, and monitor native apps with GraalVM – all inside IntelliJ IDEA? Watch @fniephaus.com's session from #IntelliJIDEAConf 👉 youtu.be/YqrEqXB59rA

openHAB, the open source home automation software, has integrated GraalPy!🤖🐍 "Unlike the Jython Scripting add-on, it offers full Python 3.11 support and is future-proof. It can be used as a scripting language in UI, file-based rules, and transformation services" www.openhab.org/blog/2025-07...

Had a fun chat with @adambien.blog about @graalvm.org and #WebAssembly. Give it a listen! 🙂

@fniephaus.com’ session, “Tips and Tricks for GraalVM and Graal Languages in IntelliJ IDEA”, is now live! Discover how to go native, embed JS/Python/Wasm, and debug it all in IntelliJ IDEA. Watch now: youtu.be/YqrEqXB59rA #IntelliJIDEAConf

🎉 Greetings from #IntelliJIDEAConf 2025! We’re just hours away from kicking off Day 1. Today’s sessions: ☕ 30 Years of Java with @sharatchander.bsky.social 🧪 Kotlin notebooks, GraalVM, AI apps & more 📺 Join us at 9:00 am UTC: youtube.com/live/Bd8EA8X...

If you are based in Prague, this is a great opportunity to learn about #GraalPy and @graalvm.org, first hand from Štěpán who's working on both!

Looking for tips & tricks for @graalvm.org and Graal Languages in @intellijidea.com? Join me at IntelliJ IDEA Conf '25 to learn how to use it to: 🌱 Compile, monitor, and debug native images 🐍 Embed Python, WebAssembly, and more in your Java apps 👉 Agenda at lp.jetbrains.com/intellij-ide...

On my way to Cologne for @jcon.one. If you want to talk about @graalvm.org, GraalPy, or GraalWasm, or just say hi, feel free to drop by the Oracle booth! 🙂

And it will be "serverless" #webassembly: you won't have to use JavaScript (unless you want to), you can use the #java you know and love with #graalvm: www.youtube.com/watch?v=Z2SW...

Join @alina-yurenko.bsky.social and me for the @graalvm.org release stream next week! We'll cover all the cool new features and improvements in GraalVM, #GraalPy, #GraalJS, and other Graal technologies!

GraalJS now supports Wasm module imports which leverage GraalWasm. Embedding the excellent Photon Rust library in JavaScript is now even simpler:

GraalPy, our Python runtime comes with lots of performance improvements, revamped native interop and a Gradle plugin for simple Python package embedding. Using a Python package from Java with Gradle is now as simple as this:

The next release of #GraalPy, #GraalJS, #GraalWasm, and other Graal Languages is out! More details in the blog post below 👇

Interesting comparison of startup and memory footprint of @graalvm.org native image vs Leyden early access build. We have btw also work underway that will allow arbitrary class loading by adding a Java interpreter to your native image. github.com/simonis/Leyd...

This is me debugging a Rust library compiled to Wasm and embedded in a @micronautfw.bsky.social microservice in @intellijidea.com: Compile with debug info, enable the Chrome Inspector for #GraalJS and #GraalWasm, and attach to the process. 🤓 Will share more details at #WasmIO later this month!

Hi folks! We're excited to be here on Bluesky, and we'll be posting lots of news, updates and release announcements here from now on. Have a happy festive season!

Give this creator of @sdkman.bsky.social a follow please! SDKMan is already awesome and it seems his new year resolution is to make it even better 👍 🚀

We just merged the current status of the upcoming JDWP support for @graalvm.org Native Image! 🥳 This will soon provide developers with the same debugging experience they are used to in Java, but for native images! Stay tuned for more details. github.com/oracle/graal...
